How to make Jinrikis sound like source voice?

[MaMochii]

Hello.

I am working on various jinrikis, for the funsies. Not gonna release them tho.
I had a question regarding those.

How do I make them sound more... like the source voice?

Per now I'm trying with moresampler but it doesn't work well for all samples. Also tried flags and other resamplers with both flags and without flags.

If I need to use flags, which are the ones that suit Jinrikis best to sound like the sourced voice?

I dont really use flags much often since their kinda hard to remember but I usually turn down the breath to 0, especially if its a character with a lot of voice effects. Sometimes it starts to sound robotic though so if it does another thing I'd reccomend is using OMAKASE to make the transitions smoother (not sure if its for PC UTAU) or putting really small vibrato on the notes that dont have it. Other than that the flags that could seem to help would be the W and H flags since they change the filter on the voice and not change the voice entirely like most flags.
